A video taken by a witness outside the store shows the suspect with his arms up in the air and what looks like an assault rifle slung around his neck as he’s being arrested.
It’s unclear what the Andreychenko's motive was, but police told ABC Springfield affiliate KSPR that the man was recording himself with his cellphone while walking through the store.
"All we know is the fact that he walked in here heavily armed, with body armor on, and military fatigues on, and caused a great amount of panic inside the store," Springfield Police Department Lt. Mike Lucas said Thursday. "He certainly had the capability and potential to harm people."
In a Facebook post from February, on a page police believe belongs to Dmitriy Andreychenko, he allegedly wrote "It's official. I hate Walmart. Apparently they won't sell Rifle and shotgun ammo if your [sic] under 21. 'New policy' However I can walk into the store with a loaded .40 and nobody says anything. What a joke."
